The warning device (12) includes a warning light mechanism (16), that is configured so as to emit a flashing strobe light (20) that flashes at a frequency that is higher than 10 Hz.

A lighting device includes a light source disposed inside of a vehicle, an external light sensor that detects illuminance of light outside of the vehicle, and a controller that controls the light source such that a lower light intensity ratio of the light source is set for higher illuminance detected by the external light sensor. The controller performs a light intensity ratio maintaining control that maintains the light intensity ratio of the light source even when the illuminance changes from a low state to a high state during a period from when a change amount of the illuminance exceeds a predetermined value until a predetermined period elapses.

A seat illuminating system (101D) for, in particular sunlight-like, illuminating a target region (144) comprises a seat arrangement (140) having a seat surface (142A). The target region (144) is defined for a person sitting on the seat surface (142A). The seat illuminating system (101D) comprises further a mounting structure (150A) being spatially fixed with respect to the seat arrangement (140); a reflector unit (106) mounted at the mounting structure (150A) and comprising a reflective surface and a luminous layer for homogenously emitting diffuse light at a first color, the luminous layer extending in front of the reflective surface and comprising a visible front area section (110A) of the reflector unit (106). The seat illuminating system (101D) comprises further a light projector (102) mounted at the mounting structure (150A) and configured to generate a light beam (103) adapted in size for comprehensively illuminating the visible front area section (110A) such that at least a portion of the light beam (103) passes through the luminous layer before and after being reflected by the reflective surface, thereby forming an illuminating light beam (103A) at a second color directed onto the target region (144).

An LED illumination apparatus includes a first lighting module, a second lighting module, a lamp cup, a heat pipe, and a plurality of heat dissipation fins. The first and second lighting modules are connected with each other and emit light in opposite directions, in addition being received by the lamp cup. The lamp cup includes two reflecting surfaces arranged in symmetrical mirror fashion. The light emitting from the first and second lighting modules are directed to respective reflecting surfaces and reflected toward a same direction by the reflecting surfaces. The heat pipe is disposed in between the first and second lighting modules. The heat dissipation fins are fitted over the heat pipe. The heat generated by lighting modules would transmit to the heat pipe and be guided to the heat dissipation fins in order to accelerate cooling.
